[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Soil remediation is a technical measure to restore the normal function of polluted soil. In the soil remediation industry, there are more than 100 soil remediation technologies, which can be roughly divided into three methods: physical, chemical and biological.

[0031] Soil remediation refers to the use of physical, chemical and biological methods to transfer, absorb, degrade and transform pollutants in the soil to reduce their concentration to an acceptable level, or to transform toxic and harmful pollutants into harmless substances. Fundamentally speaking, the technical principles of contaminated soil remediation can include: (1) changing the form of pollutants in the soil or the way they are combined with the soil, reducing their mobility and bioavailability in the environment; (2) reducing the concentration of harmful substances in the soil.

[0032] The process of soil remediation is quite long. Currently, solving the problem of soil pollution requires the joint efforts of scientists from different disciplines such as soil science, agronomy, ecology, biogeochemistry, marine science, as well as production units and government decision-makers involved in agriculture, forestry, fisheries, etc.

[0033] Soil is a natural shelter and purification site for various wastes. The fact that soil accepts pollutants does not mean that the soil is polluted. Only when the soil contains too many pollutants, affecting and exceeding the self-purification capacity of the soil, thus producing harmful effects in hygiene and epidemiology, does it indicate that the soil is polluted. There are many reasons for soil pollution, such as industrial sludge, agricultural use of garbage, sewage irrigation, deposition of pollutants in the atmosphere, and the large-scale use of mineral fertilizers and pesticides containing heavy metals.

[0034] Contaminated soil will lead to reduced crop yields and may even cause excessive pollutants in agricultural products, which will endanger human health. Soil is an important material basis for human social production activities and an indispensable and difficult-to-regenerate natural resource. Untreated contaminated sites will be chemical time bombs. Once a large-scale outbreak occurs, it will have an immeasurable impact on the country's sustainable development. Therefore, it is necessary to attach great importance to the prevention of soil pollution and the remediation of contaminated soil. Therefore, it is necessary to properly manage and remediate it so that it can be used reasonably.

[0035] With the continuous acceleration of the industrialization process, the irrational exploitation of mineral resources and their smelting emissions, long-term sewage irrigation and sludge application to the soil, atmospheric deposition caused by human activities, and the application of fertilizers and pesticides have caused serious soil pollution.

[0036] Although the soil itself has a certain purification capacity, when the amount of pesticides entering the soil exceeds the soil's environmental capacity, soil pollution will occur, which will have a serious impact on the soil ecosystem. At the same time, it will enter the human body through the food chain and cause harm to human health. In short, the hazards of soil pesticide pollution can be summarized as follows.

[0037] Impact on Crops: Pesticide residues in the soil will gradually be transferred to plants through the root activity of plants, increasing the amount of pesticide residues in plants, affecting the quality of agricultural products and causing a decline in farmers' economic benefits.

[0038] Impact on soil organisms Many pesticides will poison soil organisms, such as earthworms. Earthworms are an important soil beneficial organism. They can keep the soil loose and improve soil fertility, but some highly toxic pesticides will kill earthworms.

[0039] Different pesticides have different effects on soil microorganisms. The same pesticide has different effects on different microbial groups, but in general, pesticides can affect the population and population size of soil microorganisms. Fungicides have a greater impact on soil microorganisms, killing or inhibiting the growth of both beneficial and harmful microorganisms, such as nitrifying bacteria and ammonia-forming bacteria. In addition, pesticide residues in the soil also have a certain impact on the number of microorganisms in the soil, causing dysfunction of the soil ecosystem, imbalance, imbalance or lack of nutrients, which is not conducive to the growth and metabolism of organisms in the soil.

[0040] Impact on human and animal health Pesticide residues in the soil can be absorbed by food and vegetable crops, causing them to be contaminated and endangering human and animal health through the food chain. In addition, they can also enter the human or animal body through drinking water on the surface of the soil, causing direct or indirect harm to human health and affecting people's normal life.

[0041] Pesticide residues in the soil can also change the physical properties of the soil. Uneven nutrients will eventually lead to a decrease in the yield and quality of crops. Long-term exposure to pesticides will eventually lead to significant acidification of the soil. In addition, the soil will be contaminated by heavy metals, causing irreparable damage. When pesticide residues in the soil affect the number of certain organisms and thus the local food chain, it will seriously affect the environment. For example, pesticides reduce the number of birds through rice ears, which in turn increases the number of voles, further affecting local vegetation species and damaging the environment. In addition, the arbitrary disposal and discharge of other substances (sewage) causes pollution to the rural production and living environment.

[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] A soil shoveling mechanism is fixedly arranged on the vehicle frame 1, and is located behind the repair liquid spraying mechanism. The soil shoveling mechanism is used to shovel up the soil after the repair liquid is sprayed;

[0048] The soil screening mechanism is fixedly arranged at the rear end of the vehicle frame 1. The soil screening mechanism is located behind the soil scooping mechanism. The soil screening mechanism is used to screen the scooped soil.

[0049] Furthermore, the lifting and crushing mechanism includes a first guide rail groove 10 and a second guide rail groove 12, the first guide rail groove 10 and the second guide rail groove 12 are both vertically fixedly arranged on the top of the front end of the frame 1, the top of the first guide rail groove 10 is fixedly connected to a first motor 11, the output shaft of the first motor 11 is coaxially fixedly connected to a first lead screw, the first lead screw is rotatably arranged inside the first guide rail groove 10, the first lead screw is threadedly connected to a first slider 13, the first slider 13 is in sliding contact with the inner wall of the first guide rail groove 10, a second light rod is fixedly arranged inside the second guide rail groove 12, a second slider 14 is slidably sleeved on the outer side of the second light rod, the second slider 14 is in sliding contact with the inner wall of the second guide rail groove 12, and a crushing part is rotatably arranged between the first slider 13 and the second slider 14.

[0050] Furthermore, the crushing part includes a rotating roller 18, both ends of which are rotatably connected to the first slider 13 and the second slider 14 respectively, a plurality of crushing knives 19 are arranged on the outer wall of the rotating roller 18, and the plurality of crushing knives 19 are arranged at equal intervals along the circumferential and axial directions of the outer wall of the rotating roller 18, a second motor 15 is fixedly connected to the top end of the second slider 14, and a driving gear 16 is fixedly connected to the output shaft of the second motor 15, and a driven gear 17 is fixedly sleeved at one end of the rotating roller 18, and the driven gear 17 is meshed with the driving gear 16.

[0051] The device as a whole is pulled forward by a power machine, which can be a tractor head or an agricultural tricycle. After the device is moved to the position of the soil that needs to be repaired by the power machine, the first motor 11 works to drive the first screw to rotate, and the first screw drives the rotating roller 18 to descend through the first slider 13 until the crushing knife 19 can penetrate into the soil to a certain depth, and then the second motor 15 works to drive the rotating roller 18 and the crushing knife 19 to rotate at a high speed through the meshing action of the driving gear 16 and the driven gear 17 to crush the compacted soil.

[0052] As an embodiment that can be added to the present invention, the crushing knife 19 includes a right knife bar 1901 and a left knife bar 1902. The right knife bar 1901 is fixedly connected to the rotating roller 18, and the left knife bar 1902 is movably connected to the rotating roller 18. One end of the left knife bar 1902 is fixedly connected with an adjusting slider 42. The adjusting slider 42 is movably arranged in an adjusting cavity 43 opened in the rotating roller 18. Several adjusting sliders 42 are commonly threadedly connected with an adjusting screw 41. The adjusting screw 41 is fixedly connected to the output shaft of the adjusting motor 40. The adjusting motor 40 is fixedly embedded in the rotating roller 18. A clearance hole 44 for accommodating the left knife bar 1902 is opened on the rotating roller 18. In this embodiment, the adjusting screw 41 is driven to rotate by the adjusting motor 40, and the adjusting slider 42 can be driven to move in the adjusting cavity 43, so that the right knife bar 1901 and the left knife bar 1902 are separated.

[0055] As the device continues to move forward, the atomizing nozzle 25 moves to the top of the crushed soil. At this time, the telescopic rod 22 extends to drive the spraying pipe 24 to descend until the atomizing nozzle 25 penetrates into the crushed soil to a certain depth. The threaded tube 20 can automatically extend or shorten, so it will not affect the lifting and lowering action of the spraying pipe 24. After the atomizing nozzle 25 penetrates into the crushed soil, it sprays a mist of repair liquid mixed in the soil. The triangular blade 26 can separate the soil in front of the atomizing nozzle 25 to both sides as the device continues to move forward, so as to prevent the atomizing nozzle 25 from being damaged due to the resistance of the soil during the advancement of the device.

[0056] As an embodiment that can be added to the present invention, a synergistic crushing mechanism is arranged between the lifting and crushing mechanism and the repair liquid spraying mechanism, and the synergistic crushing mechanism includes a synergistic crushing roller and a synergistic crushing knife. The rotation directions of the synergistic crushing roller and the rotating roller 18 are perpendicular to each other, and the soil crushing direction of the crushing knife 19 and the soil crushing direction of the synergistic crushing knife are cross-shaped, thereby improving the soil crushing effect. Apart from this, the other structures of the synergistic crushing mechanism are the same as those of the lifting and crushing mechanism.

[0058] After the repair liquid is sprayed into the crushed soil, the third motor 28 starts working, driving the third slider 30 and the shovel board 32 to descend to the lowest position through the third screw, and the lower end of the shovel board 32 is inserted into the crushed soil. As the device continues to move forward, the shovel board 32 scoops up the soil and introduces it into the soil screening mechanism for filtering and screening.

[0059] Furthermore, the soil screening mechanism includes a linear motor 35, which is fixedly connected to the bottom end of the frame 1, and the output shaft of the linear motor 35 is fixedly connected to one end of a supporting frame 36.

The free end of the steel wire rope 9 passes through the through hole 7 and is fixedly connected to a cross plate 33, and the cross plate 33 is fixedly connected to the top of the filter frame 34.

[0061] After the scooped soil enters the filter frame 34, the output end of the linear motor 35 continuously moves to drive the supporting frame 36 to vibrate left and right, and the supporting frame 36 further drives the filter frame 34 and the soil inside it to vibrate at a high frequency, and the soil leaks out from the filter holes of the filter frame 34 and falls back to the ground, and the plastic, metal, glass fragments and other debris mixed in the soil are filtered and trapped in the filter frame 34. When a certain amount of debris accumulates in the filter frame 34 and affects the filtering effect, the filter frame 34 is lifted by the winch 8 and the wire rope 9, and the staff cleans out the debris in the filter frame 34, and then the filter frame 34 is re-placed in the supporting frame 36 for filtering again.

[0062] Furthermore, a plurality of running wheels 6 are provided on the frame 1 .

[0063] Furthermore, a connecting plate 4 is fixedly connected to the front end of the outer wall of the cover shell 2 .
